Did You Know?


When Joe is talking to Mrs. Demarco at her house, she is seen mixing her cocktail with an olive that's on the end of a toothpick, and initially both the toothpick and olive are in her glass in the shot of her taken from the front. Then right after that, when the camera switches to a shot of her from the back, the olive and toothpick are now no longer in the glass but are in her right hand about a foot away from the glass. When the camera then switches back to a shot of her from the front, the toothpick and olive are in the glass once again. Then right after that, in another shot of her from the front, the olive has disappeared entirely and Mrs. Demarco is now holding only the toothpick in her right hand about a foot from the glass.

A good episode up until the ending where a key loose end is left unresolved
19 April 2015 | by (Scottsdale, AZ) – See all my reviews

This episode was a pretty good and entertaining one up until the ending, where a key plot point was left unresolved.

It's about an executive who is killed in his office, and Mannix is hired by the wife of the person accused of killing him as she insists he's innocent.

There's a big problem with this episode, though. How were all of the people in the office building able to hear what was being played on the tape recorder?? Unless the sound was amplified in some way, there's no way they could have heard it, even if the volume was turned all the way up on the recorder. No indication was given on the show that the sound had been amplified and no other explanation was provided for this discrepancy, and it was simply left as a loose end. So because of that, I'm giving this show a 7 instead of a 10, which is still pretty good but it could have been a lot better.
